Modified Files:
src/lib/libc/string: strerror_r.c
Log Message:
Arrange that strerror(-1) prints "Unknown error: -1" and not the
unsigned equivalent of -1.
While here, guarantee, even when !NLS, that nothing here (not even
snprintf deciding to complain about EILSEQ or something) can ever
alter errno (ie: always save and restore it, not only in the NLS case).
The functions here must never alter errno, whatever happens.
